Sorry, but NO you cannot 'patch' the program without the source code.

 

by: kar10sPosted on 2004-07-02 at 06:09:57ID: 11456380

maybe would be possible to dissasembly the application and locate where that constant character is used, make a jump to a "free zone" and there codify in assemble language what you need.

I have do it with application in other programming language, but I do not know if it  would be possible in VB ( pedending of version and how the aplication was compiled ).

Regards

Don't expect to decompile a VB program. You have, I hope, the source. Just correct the code, recompile and re-distribute.

 

by: diegojserranoPosted on 2004-07-02 at 15:53:08ID: 11460793

>> I created an application....
then just take the source code, you still have it, don't you?

 

by: Arthur_WoodPosted on 2004-07-02 at 20:52:42ID: 11461628

to Diegojserrano and GrahamSkan>>"I dont have the Code any more. "  No, he/she no longer has the original source code.

sorry s_ishfaq, but my original answer still stands - you are OUT OF LUCK.  What you ask CANNOT be done.

Yeah, Its the fact that i have lost the code. The application is more than a year old.
Is there any method to find that constant from the compiled VB application?

 

by: GrahamSkanPosted on 2004-07-04 at 23:23:51ID: 11470997

Arthur is right. ( I missed the bit about your loss of the code)

There was an attempt at a decompiler, but it only worked at all in 16 bit versions of VB. You could, perhaps, make it your lifetime's work to write a 32 bit one.
